l To ZZ whom t 'may concern:

Bc it known that I, lloenn'r D. EAoLnsrmnD, a citizen of the United States, and a resi dent of lndianapolis, county of Marion, and State of Indiana, have invented a certain new and useful lllolding-ll/achine; and l do hereby declare that the following is a full, clear, and exact description thereof, reference beingl had to the accompanying drawv ings, 'in which like letters refer to like parts.

My invention relates to nen7 and useful improvements in molding` machines and my prime object is to provide individually oper ated and driven. cutter heads so arranged. that all faces of the timber will be cut by passing the timber once through the machine. it further objectis to provide means for longitudinally adjusting the various cutter heads Without disturbing the driving mechanism for the cutter heads. A; further object is to provide adjustable means for feeding the timber to the cutter heads; A futher object is to provide a chain drive for the feeding rolls and so arrange the same that a single chain will drive all of the rolls. A further object is to provide movable supports for certain of the eutterheads and their driving` mechanisms, whereby the cutter heads' may be adjusted with respect to the faces of the timber, and a further object is to provide means for supporting the cutter heads for cutting the side faces of the timber and the driving means there for, at various angles so that the side faces of the timber may be beveled or formed into any desired shape. o

Other objects and advantages will be hereinafter more fully set forth and pointed. out in the accompanying drawings and the following description and claims.

Figure l is a perspective view of the melder showing the operatinfv side thereof. Fig. 2 is perspective view ot the opposite side of the melder. Fig. 3 is a vertical longitudinal sectional. view through the melder. Fi a is a central vertical sec tional view tirough one` ofthe vertical motors. Fig. 5 is a side elevation otone of 'the vertical motors from a point at right angles to the View shown in Fig. 4. Fig. 6 is an elevation of one of the horizontal cutterheads and motors, and supporting means therefor, partsof said supporting means being'in section. Fig. 7 is anl elevation of the upper end ofone of the supporting arms for thehorizontal cuttenhead as seen from. .line

Specification of Letters lzatent.

Application filed September l0, 1917. Serial No. 190,516.

7 7, Fig. 6, and 8 is an enlarged seen tional view of one end of the horizontal outter head shaft and its bearing, removed fromits support.

Referring to the drawings in which simi.-

lar reference numerals designate correspond ing parts throughout the several views, l. indicates the frame of the machine which may be constructed in any preferred manner, and f 2 indicates a bed plate at the upper end of the frame over which the articles to be out are passed.

rlhe prime object of this invention is to provide cutting devices for plaifiinpA all sides of the timber as its passes over the ,ed plate, and to perform the Work simultaneously, each cutter-head being operated independ ently of the others by au individual motor. To this end, therefore, a horizontally disposed cutter--head 3 is mounted. in a snipporting frame a and so positioned that it Will cut the upper face of the timber as it passes lengthwise of the bed plate, the shaft 5 earrying the cutter-head having a motor 6 attached to one end4 thereof.

A,V similar cutter-head 7 is mounted in a supporting frame 8 at a point adjacent the rear end of the bed plate and below said bed plate; this cutter-head being employed.

for cutting the lovv'ervface of the timber.4

The cutter-head. 7 is likewise mounted upon a shaft 9, to one end of which is attached. a driving motor l0.

Between the cutter-head 3 and the cutterhead T are vertically extending cutter-heads ll and 12 which are adapted to eut the oppd site side faces of the timber, the latter cutter-heads being mounted upon vertical shafts 13 and 14. respectively., to which are attached vertically disposed motors l5 and 1G respec tively.

ln order to adjust the cutter-heads 1l and 12, and their respective motors laterally, said motors are suspended from plates 17 and 18 respectively, which. are slidaloly mounted in the bed plate Q, and movable transversely thereof. The plates l? and 18',

have depending arms 19 and 90 respectively, Which are engaged by pins 2l and 22 on the casings of the motors lo and i6. The arms 19 and 20 are preferably formed in two parts, the .lower parte 2S and 241 being held in engagement with the upper or xed parts of said arms by means of bolts 25 and 26, each part of the arm -loeingr provided With a. semercular seat through which 'the pins aio' Lasarte jection 'I3v on the frame 1 and through a bearing 7a on the standards 56, the upper ends of the screws having'gears 75 which mesh with gears 76 carried by a shaft 77, said shaft extending transversely across the top of the planer1 above the pair of adjustable rolls, said shaft having a crank 78 attached thereto for rotating the same, whereby both sides of the standards will be adjusted uniformly. v

In operation a piece of timber is placed upon the bed plate 2 and entered between the pairs of upper and lower rolls, and it is then fed by said rolls below the cutter-head 3 which planes the upper surface of the timber, then between the cutter heads 1l and 1Q which plane the side faces of the timber, and over .the cutter-head 7 which planes the lower face of the timber, thereby completing the planing operation by passing the ,timber once through the machine. lf it is desired to shape the side faces of the timber in any manner, the motors 15 and 16 are set at the proper inclination before the timber is entered between the cutter-heads 1l and 12. By providing an individual motor for each of the cutter-heads the operationvof the planer is not only simplied but the action of one cutter-head is not infiuenced by the action of the oth-er cutter-heads. The invention claimed is: 'Y'

l. In a molding machine, a cutter head, a shaft for said cutter head, a driving motor for said shaft, housings through which said shaft extends, means to move one of the housings and shafts lengthwise and move the shaft through the motor and other housing, and means to lock the housingsA against movement.

2. In a molding machine, a cutter head,

longitudinally without affecting the position of said thereof.

4. In a molding machine, a shaft, a cutter head carried by the shaft, an operating motor on said shaft, amovable plate for supporting said motor, means to adjust said plate laterally, means for adjustably suspending said motor` from said plate, and means to adjust said shaft longitudinally without affecting the position of said motor or changing the speed thereof.

`5. In` a molding machine, a cutter head, a shaft, a motor mounted upon said shaft,

motor, or changing the speed a stator iron for said motor, a rotor iron.

on said shaft, means for adjusting said shaft longitudinally, one of said irons being greater in length than the other, whereby said i ons will always remain in full contact wi h each other coincident to the longitudinal adjustment of the shaft, and not change the speed of said motor when'the shaft is adjusted.

In witness whereof, I have hereunto affixed my signature.
